NEW YORK — What were they thinking? Through plastic smiles or gritted teeth, moms have to suck it up sometimes when Mother’s Day means a gifted toilet, unsolicited wash tub or anti-aging cream.

It wouldn’t be Mother’s Day if some mom somewhere wasn’t disappointed or downright piqued at gift time. Many aren’t looking to break the bank, though the National Retail Federation expects Americans to spend $19 billion on the holiday this year. But unrequested sex toys? A chainsaw?

Dave Hochman learned the hard way last year when he presented his five-years-older wife with a “Cougar” T-shirt, a freebie from a client, no less.

“While she does have a great sense of humor, let’s just say it wasn’t the best idea I’ve ever had,” said Hochman, in Monmouth, N.J.

Glenna Tooman’s uh-oh moment was when her now-grown son, Bill, was 10 or 11. He disappeared on his bike in Boise, Idaho, only to return with a Mother’s Day gift that kept on giving, a tiny bunny.

“I was very surprised. It’s the last thing you’d expect for Mother’s Day,” she said. “He spent his allowance money on it. We named him Garfunkel. We had him for years.”

A rabbit might be better than what a good chunk of moms surveyed in March by the website Cafemom received last year — absolutely nothing. And, while vacuums have come a long way in design and efficiency, they still ranked among the worst Mother’s Day gifts ever received.

So do unrequested sex toys, guys. Like the vibrator an exhausted Ashley Largent — home with a 7-month-old — got for her first Mother’s Day in 2004, from her now ex-husband.

“That was the only present I ever received from him for Mother’s Day,” said Largent, in Gaffney, S.C. “After that I told him that I didn’t want anything.”

In San Francisco, Heddi Cundle joked that her mother back home in England hasn’t quite forgiven her for a particular Mother’s Day gift: A plastic wash tub with dish gloves and a scrub brush, all from the dollar store.

Said her mom, Bev Cundle, in Leeds: “What can I say? How does a mother smile through gritted teeth. A washing bowl in blue, not my favorite color, a square shape to fit in a round sink! And a brush to clean out mugs. How do you make it disappear?”

Other, er, unusual items to make the worst-gift list at Cafemom: a Cuban cigar and stale candy left over from Easter. One mom, RoseMarie Luevano in San Antonio, Texas, received a chainsaw two years ago.

“My husband had been wanting it so he kept telling his family about it, but they thought it was me (who wanted it) and Mother’s Day was just around the corner,” she said. “I really wanted a certificate for a spa.”

Becky Jackson has no use for fussy spas, flowers or jewelry. She lives on a ranch in Lewistown, Mont., and her jaw dropped a few years ago when her husband presented her with a long, nicely wrapped cardboard box that screamed long-stem roses.

“I tried to hide my disappointment as I slowly undid the ribbon and wrapping paper, trying to figure out how, after almost 20 years of marriage to my rancher husband, he still didn’t know I wasn’t big on flowers,” Jackson said.

Inside was a new .22-caliber rifle, “perfect for packing around on my four-wheeler to help rid our ranch of pesky critters,” she said.

Big boxes aside, moms surveyed by the site PlumDistrict said they’d choose handmade gifts over store-bought ones. And while breakfast in bed is a sweet gesture, they’d choose another one: sleeping in. In potentially difficult news for any eager gift-giver now scratching the chainsaw off his list, the surveyed moms also agreed they’d rather not have to be in on buying their own Mother’s Day gift.
